rebase: fix 'rebase onto %d starting from %s' - show root instead of list repr The debug statement is already in a 'for root in roots' so it was probably the intention to show root instead of roots. Do that.

log: describe graph symbols in the help I wondered what 'x' meant and didn't find it described anywhere.

tests: backout a82de9dc4f77, debugstacktrace is now stable, drop workaround

util: debugstacktrace, flush before and after writing Close another stream (default stdout, which often is buffered) before writing to the primary stream (default stderr, which often is unbuffered). The primary stream is also flushed after writing (in case it is buffered). This fixes non-deterministic output order, especially on windows.

run-tests.py: work when --with-hg is set to system hg Previously we'd always assume that --with-hg is a script in a user directory, and would write out a 'python' symlink to the same location. That didn't work if --with-hg was set to a system installation of hg, e.g. /usr/bin/hg. Introduce a TMPBINDIR directory which is used to write out the python symlink.

revset: added cached generated list on generatorset This allows to iterate the generatorset more than once.

templater: shorten pure integers Originally, the addition of the 'shorten' template function in 9c6b86dd2ed2 would not consider pure integers for shortening. This patch considers two simple cases: when the integer starts with zero (which is parsed by Mercurial as a hash first) and when the integer is larger than the tip (obviously not a rev).
