All the buffers related to files have FILENAME_MAX size, so it is impossible

60da4fb049 paste: fix warning on indentation in parallel()
_Bug_
Got the following error after cloning and running make:

paste.c: In function ‘parallel’:
paste.c:70:4: warning: this ‘else’ clause does not guard... [-Wmisleading-indentation]
    else
    ^~~~
paste.c:72:5: note: ...this statement, but the latter is misleadingly indented as if it is guarded by the ‘else’
     last++;
     ^~~~
This patch preserves the same functionality and just adjusts indentation to squelch the warning.

_Test plan_
Used the following 'script' to convince myself output looked correct for inputs
where the latter arguments to paste had fewer lines.

	make && printf "1\n2\n" > two.txt && printf "" > zero.txt && ./paste -d, two.txt zero.txt

Previously, if a file failed to read in a checksum list, it would be

Also, if reading from stdin failed, previously a bogus checksum would be
printed anyway.

609169d600 install: ignore -s
The -s flag previously called strip(1) on the installed file.
This patch changes install(1)'s behaviour to ignore -s.

Many makefiles use the -s flag, so it has to be recognised for
compatibility, however it does not have to do anything because
symbols do not negatively affect the functionallity of binaries.

Ignoring -s have the added benefit that the user do not need
to edit makefiles if they want the symbols that are useful for
debugging. If the user wants to strip away symbols, it can be
done manually or automatically by the package manager.

Laslo: Update the man-date and remove -s from usage()

b7fb3a58e7 xinstall: Fix broken memmove with -t
memmove moves a number of bytes, not pointers, so if you passed a number
of arguments that is larger than the pointer byte size, you could
end up crashing or skipping the install of a file and installing another
twice.

Also, argv was never decreased to match the moved arguments, so the -t
parameter was added in the NULL argv slot.

unsigned).

123f784ccc printf: handle \0 in %b arguments
The %b case was using fputs after unescape to print the argument, which
meant that it could not handle nul bytes. Instead, store the length
returned from unescape and use fwrite to properly handle them.

b7c73e2392 ed: Fix backslash expressions in RHS
By stripping backslashes this code caused a number of bugs.
'\<digit>' expressions caused literal <digit>s to be subbed-in,
'\&' was treated identically to '&', and other escaped characters
added garbage to the string.

fb11173926 tr: Fix multiple ranges with different lengths (Michael Forney)
See his description below. Thanks Michael!

---
A bug was introduced in bc4c293fe5 causing the
range length for the next set to be used instead of the first one. This causes
issues when choosing the replacement rune when the ranges are of different
lengths.

Current behavior:

$ echo 1234 | tr 'a-f1-4' '1-6a-d'
56ab

Correct behavior:

$ echo 1234 | tr 'a-f1-4' '1-6a-d'
abcd

This also fixes range expressions in the form [a-z], which get encoded as four
ranges '[', 'a'..'z', ']', causing all a-z characters to get mapped to ']'. This
form is occasionally used in shell scripts, including the syscalltbl.sh script
used to build linux.

bc4c293fe5 Revamp tr(1) set parsing and handling
If you look at GNU coreutils, they do not support the mappings

	$ echo "1234abc" | tr "[:alnum:]" "[:upper:]"

	$ echo "ABCabc" | tr -c "[:upper:]" "[l*]"

to only give a few examples. This commit broadens the scope of tr(1)
as far as humanly possible to map between classes and non-classes,
making tr a usable tool and actually fulfilling user expectations.
Posix really is of no help here as it still kind of assumes the
fixed ASCII table instead of complex Unicode code points or even
Grapheme clusters.

9de401a495 Fix tr(1) squeezing
Okay, it took me a while and another look at the Posix spec to see that
I have been dealing with squeezing in a way too complicated way.
What just needed to be done is before doing the final write to deploy
the squeeze-check. We actually do not need this atomically complicated
squeeze check in every single edge-case. Now it should work properly.

e3f497e1f6 subtract 'a' from indices for marks
Given:

static int marks['z' - 'a'];
marks[c];

In this case c is the character read and index is out of bounds. We
need marks[c - 'a']

While playing around with optimization settings gcc caught caught this.

Also fix one check for c, change from isalpha to islower.
