annotate hgrunner.cpp @ 195:ff0d76dcb3b8

* Don't close proc input on finished() -- causes crash on program failure on Windows * Use merge binary from settings, even if empty -- sometimes user may wish to set an empty string to avoid having an external merge program * Revert labels to line edits in settings dialog, for a similar reason (permit setting empty value) * Avoid showing hard hyphens on Windows, they don't look right * Use preformatted text for merge outcome dialog (but format3 would be better)
