When the input file ends with a C++ style "//" comment line, without a
newline at the end, the parser will attempt to read past the end of
the input buffer. This produces undefined results, among them putting
the parser in a bogus state that makes all subsequent input files
parse incorrectly. Here's a possible fix:
--- old/ebrowse.c 2010-04-03 15:26:07 -0700
+++ new/ebrowse.c 2010-11-19 16:36:13 -0800
