Add a couple of extra docstring backslashes, #'format-time-string
2010-09-05 Aidan Kehoe <kehoea@parhasard.net>
* editfns.c (Fformat_time_string):
Use two backslashes so that there is at least one present in the
output of describe function, when describing the Roman month
number syntax in this function's docstring. Thanks for provoking
me to look at this, Stephen Turnbull.
