util: add the code path to "cachefunc()" for the function taking no arguments
Before this patch, "util.cachefunc()" caches the value returned by the
specified function into dictionary "cache", even if the specified
function takes no arguments.
In such case, "cache" has at most one entry, and distinction between
entries in "cache" is meaningless.
This patch adds the code path to "cachefunc()" for the function taking
no arguments for efficiency: to store only one cached value, using
list "cache" is a little faster than using dictionary "cache".

When Mercurial accepts more than one revision, they may be specified individually, or provided as a topologically continuous range, separated by the ":" character. The syntax of range notation is [BEGIN]:[END], where BEGIN and END are revision identifiers. Both BEGIN and END are optional. If BEGIN is not specified, it defaults to revision number 0. If END is not specified, it defaults to the tip. The range ":" thus means "all revisions". If BEGIN is greater than END, revisions are treated in reverse order. A range acts as a closed interval. This means that a range of 3:5 gives 3, 4 and 5. Similarly, a range of 9:6 gives 9, 8, 7, and 6.
