It all depends on context.  In general, "the repository" is a collection
of revision histories of files.  The term is also used (imprecisely) to
mean the location of that collection, the name of that location, or a
particular subset of any of the above.

That should more properly be: "so the repository *specification* ..."

That's the location of the repository in this example.

Reading the manual first would have been a lot better option -- it
clearly states that it's the current directory name within the
repository that's matched against the regular expressions.

No.  Comments in the code are not user documentation and thus are likely
to use jargon and other shorthand.  In this case, "repository name" is
being used to mean "name of a particular directory in the repository".

Which you would have known had you read the manual.

Once again, that's a jargony or shorthand usage of "repository name"
which should have been clear from the context created by the first
