I am currently experiencing some sluggishness in the following way
using `emacs -Q' that locally visits the file at
http://git.savannah.nongnu.org/cgit/tice.git/plain/internals/v1/v1_internals_program.hpp?id=6ed1f0b6d977eccf91386ead562e10e6801e95aa:
M-g g 2874
C-u 17 M-f
M-DEL remaining (this should be a bit sluggish)
M-d M-d M-DEL source_node_ids (this is sluggish)
Would you kindly see if you experience the same thing, please? If so,
would it be easy to fix? Thank you.
