Hi,
this is so wide spread that I hesitate to sent a patch.
I: lyx: spelling-error-in-binary ./usr/bin/lyx collapsable collapsible
I: lyx: spelling-error-in-binary ./usr/bin/tex2lyx collapsable collapsible
It's even in a file name src/insets/InsetCollapsable.cpp.
Is someone interested to fix this in the internal parts aswell?
Both spellings appear to be acceptable, at least according to some
dictionaries. The OED gives only "collapsible", but lists "collapsable"
as the earliest occurence, in 1845. Random House and American Heritage
give both spellings. The "i" version seems to be preferred, however.
