org-table-copy-down feature request

[Marcin Borkowski <mbork@wmi.amu.edu.pl>]

Hi Org Devs and Users,

at present, the only reasonable values of org-table-copy-increment are
nil or non-nil.  How about enabling to use it as an increment value?
This would be very useful in the following case: I want to make a table
with dates for subsequent classes (and table is better than headlines
for me, since for each class I put - among others - the number of
problems solved during that class, so that I can use the spreadsheet to
compute the total and average-per-hour numbers; useful for planning for
the remainder of the semester;)).  It would be great to set
org-table-copy-increment to 7 so that I get timestamps increased by one
week.

Another change which would help me might be to have a special value like
'arithmetic, so that the increment could be computed from /this and
previous/ entries. (This might be even better, mimicking
Excel's/LibreOffice's functionality, which is a bit broken in those
applications, since it seems to require a mouse, but is very useful
nonetheless.)

Another, related problem I have with org-table-copy-down is that it
overwrites rows.  It might be better for it to insert a new row /if/
the entry in the next row is nonempty.

What do you think?
