#2560: remove an unnecessary 'for' loop from my_fgets() in Parser/myreadline.c.

Noted by Joseph Armbruster; patch by Jessica McKellar.

The original code was 'for (;;) {...}', where ... ended
with a 'return -2' statement and did not contain a 'break' or 'continue'
statement.  Therefore, the body of the loop is always executed once.

Once upon a time there was a 'continue' in the loop, but it was removed in
rev36346, committed by mwh on Wed Jul 7 17:44:12 2004.
