[ESS] jumping to a function's definition

[Tim Hesterberg]

You can create a TAGS file for use with R/S code.

Here, for example, is the beginning of my TAGS file for use
with the resample library:


resample/funs/First.q,31
.First.lib <-.First.lib
3,122

resample/funs/abc.q,159
limits.abc _limits.abc
11,394
limits.abc.default <-limits.abc.default
30,926
limits.abc.resamp _limits.abc.resamp
451,15519
print.abc _print.abc
489,16791


I'll attach two files; one a script for updating the TAGS file,
and the other containing regular expressions for use in updating.
