setup: prefer using the system hg to interact with the local repository
Add a findhg() function that tries to be smarter about figuring out how to run
hg for examining the local repository. It first tries running "hg" from the
user's PATH, with the default HGRCPATH settings intact, but with HGPLAIN
enabled. This will generally use the same version of mercurial and the same
settings used to originally clone the repository, and should have a higher
chance of working successfully than trying to run the hg script from the local
repository. If that fails findhg() falls back to the existing behavior of
running the local hg script.
$ cat > patchtool.py <<EOF
> import sys
> print 'Using custom patch'
> if '--binary' in sys.argv:
> print '--binary found !'
> EOF
$ echo "[ui]" >> $HGRCPATH
$ echo "patch=$PYTHON ../patchtool.py" >> $HGRCPATH
$ hg init a
$ cd a
$ echo a > a
$ hg commit -Ama -d '1 0'
adding a
$ echo b >> a
$ hg commit -Amb -d '2 0'
$ cd ..
This test checks that:
- custom patch commands with arguments actually work
- patch code does not try to add weird arguments like
--binary when custom patch commands are used. For instance
--binary is added by default under win32.
check custom patch options are honored

Issue2417: hg import with # comments in description
Prepare source repo and patch:
$ rm $HGRCPATH
$ hg init c
$ cd c
$ printf "a\rc" > a
$ hg ci -A -m 0 a -d '0 0'
$ printf "a\rb\rc" > a
$ cat << eof > log
> first line which can't start with '# '
> # second line is a comment but that shouldn't be a problem.
> A patch marker like this was more problematic even after d7452292f9d3:

> # User lines looks like this - but it _is_ just a comment
> eof
$ hg ci -l log -d '0 0'
$ hg export -o p 1
$ cd ..
