cfc37be486 Do not try to rematch patterns with ^ or $
It is impossible to rematch a pattern which has one (or both)
of these operators, so the simplest solucion is detect them
while we are compiling the regular expression and break the
match loop after the first iteration.

cf868c8eeb Stop matching when lastmatch points to '\n'
This situation happens with something like s/$/test/,
where rm_so == rm_eo == 0. Without this check, ed
keeps looping forever.

0b117ab6c0 Fix pattern substitution
Ed was falling doing substitution different of the first or all
(s//%/, s//%/\1, s//%/g), because it was not adding the matches
which were not going to be substituted.

54ad6d512b Fix rematch()
Rematch() was incremnenting the last match always, even in the
cases when it was not matching anything. This patch detects
this situation and it updates it only when there is a match.

78fd6ff239 Handle explicitly the case of line 0
Line 0 is a special line added to allow operations with
empty buffers, and we have to ensure that it is not going
to match any regular expression. The code was written in
a way that this case was handle implicitily, but this
solution was working only for the first file loaded in
ed, while the second file loaded in ed got a line with
a dirty seek field. This solution check explicitily
against invalid lines passed to makeline(), which
allows to simplify the common case.

36e2bdf517 ed: Use TMPDIR to locate the temporal file
The current behaviour of storing the scratch file in
the current directory is a bit painful, because it
generates files in all the directories where you
execute ed. BSD ed uses TMPDIR for this purpouse,
so if the user wants to put the scratch file in
other place different of /tmp it only has to set
this variable.

cf0a0fc940 ed: Fix error introduced in b19d708
This patch introduced init() function, which removed the initialization

b19d708923 ed: add init()
These funcction initializes the scratch buffer, and in case of
having a file name parameter it loads the file in the scratch.
It also fixes a problem before this version, where the saved
filename was not set when the file didn't exist.

03d27b7806 ed: Reset modflag in clearbuf()
For the same reason we don't care about the state of
the buffer in clearundo() we can reset modflag in
clearbuf(), because after calling it we don't want
to know anything about the previous state.

58c9739532 ed: Move modflag=0 to clearundo()
When we discard the content of an undo buffer
is because we don't need it anymore, and it means
that we don't care about the modify state of the buffer
so we can reset the modflag in clearundo(), and
remove this assignation each time clearundo() is called.

94e92d9cc0 Refactor eprintf.c
When we move the exit() out of venprintf(), we can reuse it for
weprintf(), which basically had duplicate code.
I also renamed venprintf() to xvprintf (extended vprintf) so it's
more obvious what it actually does.
