log: add a "graphwidth" template variable
Wrapping text in templates for 'hg log --graph' can't be done very well,
because the template doesn't know how wide the graph drawing is. The edge
drawing function needs to know the number of lines in the template output, so
we need to also determine how wide that drawing would be before we call the
edgefn or evaluate the template.
This patch makes edgefn compute the graph width and pass it into the template
so that we can do something like this:
COLUMNS=10 hg log --graph --template "{fill(desc, termwidth - graphwidth)}"
@ a a a a
| a a a a
| a a a a
o a a a
|\ a a a
| | a a a
| | a a a
Using extensions to do this would be relatively complicated due to a lack of
hooks in this area of the code.
In the future it may make sense to have a more generic "textwidth" that tells
you how many columns you can expect to fill without causing the terminal to
wrap your output. I'm not sure there are other situations to motivate this yet,
or if it is entirely feasible.

#require execbit
b51a8138292a introduced a regression where we would mention in the
changelog executable files added by the second parent of a merge. Test
that that doesn't happen anymore
$ hg init repo
$ cd repo
$ echo foo > foo
$ hg ci -qAm 'add foo'
$ echo bar > bar
$ chmod +x bar
$ hg ci -qAm 'add bar'
manifest of p2:
$ hg manifest
bar
foo
$ hg up -qC 0
$ echo >> foo
$ hg ci -m 'change foo'
created new head
manifest of p1:
$ hg manifest
foo
$ hg merge
1 files updated, 0 files merged, 0 files removed, 0 files unresolved
(branch merge, don't forget to commit)
$ chmod +x foo
$ hg ci -m 'merge'
this should not mention bar but should mention foo:
