Coding question

[Steve Perrault]

Our corporate customers use their full email address to fetch their mail 
with another POP agent.  To keep convention, we configure our normal ISP 
customers to use "[EMAIL PROTECTED]", or "[EMAIL PROTECTED]" for the rare 
mail clients which balk at "[EMAIL PROTECTED]@popserver".

In trim_domain(), in pop_user.c, I replace the line:

char *r = strchr ( q, '@' );

with,

char *r = strpbrk ( q, "@%" );

Is the library function, strpbrk() common enough to use in a future 
releases instead of strchr()?  Is it worth making this very minor change to 
the source when I upgrade, or is it save to assume my clients are using 
smarter email clients nowadays?
