[TxMt] User authentication when pushing in Mercurial bundle

[S. Moon]

While switching from the terminal version of Mercurial to the
Mercurial bundle, I have found out that it doesn't seem to support
user authentication. While many repos do not use authentication, the
one I am working on uses authentication when pushing to the central
repo.

Am I missing something, or is it simply something that isn't supported?

Your very best,
