Subject: Replaced 'Limits' with 'Notes'.
X-Git-Tag: V2.15~17
X-Git-Url: https://git.sur5r.net/?a=commitdiff_plain;h=15c64c39268a24e4470096cf3bee85bf3ef1e027;p=cc65

Replaced 'Limits' with 'Notes'.

Quite some items in the 'Limits' sections aren't actual limitations so it seems appropriate to just use a more neutral term.
