repoview: fix corrupted hiddencache crash Mercurial (issue5042)
Before this patch if the hiddencache existed but was empty, it would crash
mercurial. This patch adds exception handling when reading the hiddencache to
avoid the issue.
When encountering a corrupted cache file we print a devel warning. There would
be no point in issuing a normal warning as the user wouldn't be able to do
anything about the situation.
The warning looks like:
devel-warn: corrupted hidden cache, removing it at: /path/to/repoview.py
