GNU Parallel Bug Reports Two simple requests with reasoning: timeout suffix and --dry-run short name

[paralleluser]

Dear Ole,

Please consider my 2 simple requests.  Both should take less then 30 seconds to 
program.


Simple Request #1.............

Suggest that "--timeout" follow the same syntax as GNU Core Utils timeout.  
Basically allow a s/m/h/d suffix with s being the default for 
seconds/minutes/hours/days.

man timeout|egrep "second|hour"
DURATION  is  a  floating point number with an optional suffix: 's' for seconds 
(the default), 'm' for minutes, 'h' for hours or 'd' for days.


Simple Request #2.............

Suggest there be a short notation for --dry-run.  It is commonly used but long 
to type.

GNU Parallel has established a precedent to use multiple argument notations for 
the same option (number of jobs has --jobs, -j, -P, and --max-procs)

What should a short version of "--dry-run" be?

Rsync uses both "--dry-run" and "-n", but "-n" is already taken in GNU 
parallel.  Too bad, the symmetry would be useful.

There is a precedent in GNU Parallel, to use a short double-dash such as 
"--lb", for "--line-buffer".
 
Therefore, suggest "--dry" and/or "--dr" be an additional shortcut(s) for 
"--dry-run".  I actually vote for both as I almost never run a GNU parallel 
without using --dry-run first.

Much thanks,
Parallel User
