Hi,

landry@ reported recently that login.conf(5) man page missed to document
"infinity" value for fields like "datasize-cur".

After looking at code in lib/libc/gen/login_cap.c (specially
login_getcapsize() and strtolimit() functions), valid "infinity" values
are:
- infinity
- inf

The following diff adds a sentence to "size" argument type description,
to mention the both keywords.

I reused the wording in getrlimit(2).
