branchmap: improve invalid cache message when reading
This factors out the generation of the message. This helps future error reporting
when reading cache for filtered repository.
$ hg init
Issue562: .hgignore requires newline at end:
$ touch foo
$ touch bar
$ touch baz
$ cat > makeignore.py <<EOF
> f = open(".hgignore", "w")
> f.write("ignore\n")
> f.write("foo\n")
> # No EOL here
> f.write("bar")
> f.close()
> EOF
$ python makeignore.py
Should display baz only:
$ hg status

$ rm foo bar baz .hgignore makeignore.py
