It is adding hyphenless break points to file specifications and URLs.
This is mentioned in the groff_man(7) page.
When rendered by groff to a TTY or PostScript output de‐
vice,
Contact
.MT fred.foonly@\:fubar.net
Fred Foonly
.ME
for more information.
displays as: “Contact Fred Foonly ⟨fred.foonly@
fubar.net⟩ for more information.”.
The use of ‘\:’ to insert hyphenless discretionary
breaks is a groff extension and can be omitted.
The overall function of makevarescape.sed is explained around line 825
of the "Makefile.am" file.

This looks like it might have been double-pasted...is that right?

Maybe it wasn't double-pasted. If not, then I feel like a ./configure
prefix setting of this complexity was not anticipated by groff, and
possibly not by other software using GNU Autotools, either.
Please confirm:
You can
cd
/Users/fultonm@ca.ibm.com/Documents/Development/mine<mailto:--prefix=/Users/fultonm@ca.ibm.com/Documents/Development/mine>
on these systems?
