Fix bug 10074 (regression)

Browse Source 
This was a regression of 8aa37c43. I did not take into account that end_pos
could be -1, so the code that checked whether a pair of braces needs to be
inserted between two hyphens did not work for that case. Now we check for
the length of text_, which should be done anyway, and only take end_pos into
account when it is not -1.
