Apple's default file system, HFS+, is case insensitive and monotone is
currently bad at handling case (in)sensitiveness, on Mac as well on
Windows. The reason is simply that the file system reports for both
paths, the old and the new, that the file exists and we cannot do much
about that.

Two possible "fixes" come into my mind here - one would be to
temporarily rename "heccer" to something else, commit and then rename it
from that to "Heccer". This is a bit ugly because it creates unneeded
history. The other is to manually change the workspace' parent revision
in _MTN/revision to the new, anticipated revision, removing
"glue/swig/python_old/heccer" and to mtn revert
"glue/swig/python_old/Heccer". If more files changed, these needs to be
"reverted" as well, since they could otherwise be accidentially
committed as reverse changes.

Thomas.
