Indeed. My contention is that it actually is following its normal behaviour in
both--ending insert mode. Abbreviations are a user customisation, just as
mappings
are, which modify the normal behaviour of <Esc> when it occurs after certain
user-defined words. As such, it should be excluded from a noremap, IMHO. The
whole
point of a noremap is to avoid such things to get unmodified behaviour, i.e. as
if
the user hadn't made customisations. If abbreviations are expanded in a
noremap,
suddenly it becomes difficult to reliably enter text using a mapping--you have
to
use <C-C> and then re-enter insert mode or insert arrow keys or <C-V> or
something
every time you want to end a word, just to avoid it changing due to some
abbreviation you don't know about.
In my earlier email, pretty much everywhere I wrote 'mapping' I meant a
'noremap'
mapping, too; that may well have confused the issue.
Ben.
