[PATCH 02/18] doc/bash.1: fix bug in new `Q` macro

[G. Branden Robinson]

I didn't pay close enough attention to Documenter's Workbench 3.3 troff
output when submitting the original version of this macro.  Add a
necessary backslash to escape the newline at the beginning of a
conditional block.  This omission was causing DWB to put a blank line on
the output every time it hit a "Q" macro call.  This did not delete any
text from the output, but it was surely ugly.

Diff of rendering (DWB):
-                 one with the highest index) is
-
-                 "main".  This variable exists only when a shell func-
-                 tion is executing.  Assignments to FUNCNAME have no
-                 effect.  If FUNCNAME is unset, it loses its special
-                 properties, even if it is subsequently reset.
