11:38:06: This is Geany 0.21 (svn >= r5734).
One problem with Find Usage is that after finding the usage of a keyword and after the Messages pane pops up, copying a given line using the c-menu will subsequently result in pasting the full:
aly-tc.R:1076: x.count.ids(c('permco', 'permco.tci'), xd)
instead of pasting the raw line, as found in the Editor pane:
x.count.ids(c('permco', 'permco.tci'), xd)
This comes on top of the potential improvements described in these two artefacts.  What do you think?
