The current file's directory is expand('%:p:h'). So you could use (untested)
function CurFileRelPath(path)
let hasdoswin = has('win32') || has('win64') || has('win16')
\ || has('dos32') || has('dos16')
if a:path[0] == '/'
return a:path
endif
if hasdoswin && (a:path[0] == '\' || a:path =~ '^\a:')
return a:path
endif
let prefix = expand('%:p:h')
if prefix[-1:] != '/'
\ || (hasdoswin && prefix[-1:] != '\')
let prefix .= '/'
endif
return prefix . a:path
endfunction
Then you could invoke it anywhere in a command typed at the command-line
by means of Ctrl-R followed by =CurFileRelPath('something') then Enter.
'something' (which you should enter with the quotes) will be resolved as
a relative path unless its first character (or its first one or two
characters in Dos or Windows) seem to indicate an absolute path. I'm not
treating x:abcd (which is relative to Drive X's current directory) as a
relative path, this is intentional.
Note that expand('%:p:h') will usually not end in a path separator, but
for the root directory of a Dos drive or of the whole Unix filesystem it
will, hence the last ":if" above.
