[PATCH] initialize buf2 properly

[Julius Plenz]

I don't see why you would want buf2 to be static in nature. If you have
a file that contains a single newline, for example, parse_date() returns
-1. buf2 still contains the previous date's file.

Consequently, if you call read_agefile() several times in a row, the
stack might just contain the previous date still. Thus, there's a need
to initialize it properly.
