exchange: use pushop.repo instead of repo

rebase: factor out nothing to rebase return code A rebase call that results in nothing to rebase might be considered successful in some contexts. This factors out the return code from places where hg determines that there is nothing to rebase, so an extenion might change this return code to be something that would allow scripts to run without seeing this as an error.

gitweb: 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.

rebase: added comments Added comments describing the state variable and constants used throughout the rebase extension

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).
