bug#17472: [PATCH] dfa.c (lex): Remove capitalisation of two dfaerror strings

[behoffski]

A few months ago, "make syntax-check" would complain if any string that
was subject to localisation started with an upper-case character.
Almost all messages in Grep conform to this standard.  However,
"make syntax-check" no longer complains about two cases in the current
master (dfa.c, function lex ()):

    dfaerror (_("Invalid content of \\{\\}"));
    dfaerror (_("Regular expression too big"));

I don't know if this constraint is being relaxed, or if the check has
changed somehow.  (Is syntax-check provided via gnulib?)

Attached is a simple patch that converts the two error strings above to
have a lower-case first character.  This may be useful to help maintain
consistent message formatting.
