I would say '[:,]', since both ':' and ',' might indicate a multi part
path. Extreme example:

ralf@skye:~$ kpsewhich --var-value=SYSTEXMF
/var/lib/texmf,/usr/local/share/texmf:/usr/share/texmf:/usr/share/texmf-{texlive,tetex}

PS: According to the begining of texmf.cnf the usage of ',' is
deprecated. Is that new?
