run-tests: set a default largefiles usercache in the default hgrc file
This fixes a test failure introduced in 4be754832829 on Windows and OS X, where
the cached largefile wasn't being deleted because the named .cache directory
didn't exist. It only existed on Linux because the test suite sets $HOME to the
directory of the test being run, and Linux uses $HOME/.cache by default.
Most of the other largefiles tests explicitly set this value at the top of their
scripts, but test-largefiles-update.t didn't pick that up when it was created.
Those scripts that do set a value will override this.
We could just set the parameter in the test-largefiles-update.t script, but
there are a few other non obvious tests that exercise largefiles too. These
largefiles end up being cached in the user's real cache, so proper hygiene
dictates that this not be left to each individual test script.
Initial setup.
$ hg init repo
$ cd repo
$ touch thefile
$ hg ci -A -m 'Initial commit.'
adding thefile
Create a tag.
$ hg tag branchortag
Create a branch with the same name as the tag.
$ hg branch branchortag
marked working directory as branch branchortag
(branches are permanent and global, did you want a bookmark?)
$ hg ci -m 'Create a branch with the same name as a tag.'
This is what we have:
