fopen()-pclose() bug in install-info

[Barath Aron]

Hello,

I ran into a bug in the "install-info" program, where the "dir" file is 
opened with fopen(), and it was closed with pclose(). That's why 
"install-info" hangs on the OS I use.
The path in the code is clear.

install-info/install-info.c:
910: f = open_possibly_compressed_file (...)
700: f = fopen (*opened_filename, FOPEN_RBIN);
# this might be executed, but won't make any difference
882: f = freopen (*opened_filename, "r", f);
888: return f;
939: pclose(f);

I was able to get this work with the attached patch file, based on the 
comments and the code around it.

Please fix this issue.

Regards,
Aron
