mdocml: The previous commit to this file broke the control flow keywords

[schwarze]

Log Message:
-----------
The previous commit to this file broke the control flow keywords \{ and \}
when they immediately follow a request or macro name, without intervening
whitespace.  Minimal fix.

The lesson learnt here is that, despite their appearance, \{ and \} are
not escape sequences, so never skip them when parsing for names.
