monoblue: visually highlight source lines when hovering over line numbers Due to how the line links now reside outside of the source lines, hovering over line numbers doesn't count as hovering over the appropriate source line. It can be worked around by using a "+" css selector. However, it's necessary to reorder the elements and put <a> before <span> (which is actually quite logical). It works without further css tweaks because <a> is already absolute-positioned and so the order doesn't matter visually.

monoblue: make the size of line links bigger to cover line numbers better Due to how the line numbers in monoblue are formed (via css counters), the size of the area with the numbers and the size of the actually clickable links are not tied together well enough. Before this patch, there were noticeable "gaps" between line links - clicking on the bottom part of a visible line number did nothing as opposed to selecting this line. Let's set font-size for everything in pre.sourcelines so that it also affects the links and then add a bit of padding to them so compensate for layout differences. This way the sizes are still not 100% the same, but should be very close.

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. [1] https://msdn.microsoft.com/en-us/library/windows/desktop/ms684175(v=vs.85).aspx [2] https://selenic.com/pipermail/mercurial/2015-August/048627.html

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.)
