gitweb: don't drop current revision context on graph page
In hgweb, some pages have a context of current revision; e.g. changelog and
shortlog show changesets starting from this current revision. However, some
gitweb templates were dropping current revision from some urls _to_ /graph page
and _on_ that page. This patch fixes it.
util: also catch IndexError
This makes life so, so much easier for hgwatchman, which provides a named tuple
but throws an IndexError instead of a TypeError.
exewrapper: add comments about PYTHONHOME
This has been a repeating source of confusion for users of HackableMercurial.
Note that users of HackableMercurial should *not* and are *not* expected to set
PYTHONHOME.
exewrapper: report name of failed private DLL in error message
Same as in preceding change, but this time it's for the private Python of
HackableMercurial (in hg-python directory next to the hg.exe).
exewrapper: report name of failed DLL in error message
This uses C string literal concatenation.
Example output:
$ hg version
abort: failed to load Python DLL python27.dll
Note that HGPYTHONLIB does not contain the trailing .dll, which works here
because the documentation of LoadLibrary [1] says, that if no file name
extension is specified in the filename parameter, the default library
extension .dll is appended.
See [2] for a motivation of this change.

merge: abort on file/directory case folding collisions (
issue4892)
File/directory case folding collisions cannot be represented on case folding
systems and have to fail.
To detect this and abort early, utilize that for file/directory collisions, a
sorted list of case folded manifest names will have the colliding directory
right after the file.
(This could perhaps be optimized, but this way of doing it also has
directory/directory case folding in mind ... which however not is handled yet.)
