Get-command-sequence
Return list of commands that are between two command descriptors
Examples:
(get-command-sequence 4 12)
:gcs 4 12 ; same as above
(get-command-sequence 4 :x)
:gcs 4 :x ; same as above
See pcs for a utility that prints abbreviated information about the
commands that are between two command descriptors. The utility
get-command-sequence — or simply gcs, so that you can just
type :gcs at the prompt — has the same syntax but instead of
printing, it simply returns the corresponding list of commands. More
precisely, it returns an error-triple (mv erp val state) such that
if erp is not nil, then val is the desired list of
commands.
