Log:
MFC r349376: Fix strsep_quote() on strings without quotes.
For strings without quotes and escapes dstptr and srcptr are equal, so
zeroing *dstptr before checking *srcptr is not a good idea. In practice
it means that in -maproot=65534:65533 everything after the colon is lost.
The problem was there since r293305, but before r346976 it was covered by
improper strsep_quote() usage.
