Al, thanks. The first part of bandit includes : if exists("syntax_on")
| syntax reset | endif .
Does this mean that bandit does not use color/highlighting specific to
the programming language being edited?
Al, hope you don't mind my "butting in"...
Vim has language specific syntax recognition files. These are typically
under vim72/syntax/; they are not colorschemes. They map lexical
constructs/syntax to highlighting group names.
Colorschemes map highlighting-group names (such as Statement, Number,
Special, ...) to specifications for actual colors. They typically fall
under vim72/colors/ .
Now, the test you see checks if syntax highlighting is enabled, and if
its not, attempts to restore colorscheme highlighting defaults.
So the if exists("syntax_on") ... test has nothing to do with
"using color/highlighting specific to the programming language".

However, most syntax scripts also define "default settings" for some or
all of the highlight groups they define. These settings are usually
links to the default groups, but not always. For instance,
$VIMRUNTIME/syntax/html.vim includes
if !exists("html_my_rendering")
hi def htmlBold term=bold cterm=bold gui=bold
hi def htmlBoldUnderline term=bold,underline
cterm=bold,underline gui=bold,underline
hi def htmlBoldItalic term=bold,italic cterm=bold,italic
gui=bold,italic
hi def htmlBoldUnderlineItalic term=bold,italic,underline
cterm=bold,italic,underline gui=bold,italic,underline
hi def htmlUnderline term=underline cterm=underline
gui=underline
hi def htmlUnderlineItalic term=italic,underline
cterm=italic,underline gui=italic,underline
hi def htmlItalic term=italic cterm=italic gui=italic
endif
which can be regarded as "highlighting specific to the HTML language".
Examination of $VIMRUNTIME/syntax/syncolor.vim shows that it resets only
the highlight groups which have a compiled-in default in Vim. Other
groups, if linked to one of these, get default colours by virtue of
their link, and if set to a definite value (like the ones above) keep
their highlight.
Some colorschemes set values for only a restricted set of highlight
groups, leaving the rest at their defaults. (The most extreme case of
this behaviour is exhibited by $VIMRUNTIME/colors/default.vim). If you
use ":syntax enable" when such a colorscheme is in use, both the
defaulted highlight groups and those set by the colorscheme will be
reset appropriately. (I know this isn't the object of the question.)
Best regards,
Tony.
