Absolutely negligible. If you add 10KB to a docstring (i.e. a *lot* more
text), that will add in the order of 10-20KB to the Emacs process on the
conditions that the user has looked at that docstring. I.e. it will bump
the process's size from maybe 10MB to 10.02MB. If you add 10KB to each and
every docstring ever written, then the process size will grow by about 10KB
times the number of docstring viewed in *Help*.
Absolutely negligible.
