test-merge-tool: Make sure no hgmerge can be found in $PATH
The merge tool selecting algorithm is hardcoded to look for hgmerge in $PATH
before it falls back to use internal merge. This fixes the test for this
fallback to be tolerant to existing hgmerges.
#!/bin/sh
# test that a commit clears the merge state.
hg init repo
cd repo
echo foo > file
hg commit -Am 'add file' -d '0 0'
echo bar >> file
hg commit -Am 'append bar' -d '0 0'
echo % create a second head
hg up -C 0
echo baz >> file
hg commit -Am 'append baz' -d '0 0'
echo % failing merge
HGMERGE=internal:fail hg merge
echo resolved > file
hg resolve -m file
hg commit -m 'resolved' -d '0 0'
echo % resolve -l, should be empty
hg resolve -l
