 Try to avoid the "=", "a" and "s" return values, since Vim often has to search
 backwards for a line for which the fold level is defined.  This can be slow.
 
+An example of using "a1" and "s1": For a multi-line C comment, a line
+containing "/*" would return "a1" to start a fold, and a line containing "*/"
+would return "s1" to end the fold after that line: >

 |foldlevel()| can be useful to compute a fold level relative to a previous
 fold level.  But note that foldlevel() may return -1 if the level is not known
 yet.  And it returns the level at the start of the line, while a fold might
