I had a quick look at the code in trunk, and it seems that the regexps
are compiled on line 1749 and 1775:

This regexp does not contain AP_REG_NOTEOL/PCRE_NOTEOL.

The only place NOTEOL is added is in ap_directory_walk() in line 1172 of
I presume it adds that this function walks through a bunch of regular
expression and its to _all_ regular expression, including the
DirectoryMatch where it should not be added.

Right now I don't understand why ap_directory_walk() adds this flag, but
aside for that, would it be an option to remove the AP_REG_NOTEOL from
request.c, and instead add it to the places where all these regexps are
compiled (thus add them to the ap_pregcomp() calls) instead?
It's probably more work (making sure you miss no ap_pregcomp()), but
that would work, and is probably a better solution than some \Z hack (of
which I'm not sure it works).
