hghave: be more tolerant to rst2html output
On Windows, rst2html.bat calls rst2html.py, printing something like:
"rst2html.py (Docutils"
(notice the extra ".py")
#!/bin/sh
echo "[extensions]" >> $HGRCPATH
echo "graphlog=" >> $HGRCPATH
echo "rebase=" >> $HGRCPATH
rm -rf repo
hg init repo
cd repo
echo A > a
echo >> a
hg commit -AmA -u test -d '0 0'
echo B > a
echo >> a
hg commit -mB -u test -d '1 0'
echo C > a
echo >> a
hg commit -mC -u test -d '2 0'
hg up -C 0
echo D >> a
hg commit -AmAD -u test -d '3 0'
hg glog --template '{rev}:{desc} {node|short}\n'
hg rebase -q -s 1 -d 3 2>&1 | grep -v 'saving bundle'
hg glog --template '{rev}:{desc} {node|short}\n'
