Hi
David found a bug in the recent notmuch hello saved searches and
reduced to a small test case. The problem occurs if the user sets
notmuch-saved-searches and then loads notmuch. The reason is that the
defcustom calls some utility functions and these need to be defined
(not just declared) when the defcustom is encountered.
This patch moves the code around so that they are defined first. I
have marked the patch WIP as I am not sure what the best reordering
is, and we may want to rename some functions which have changed file
for namespace reasons.
Anyway this fixes the test case. If it fixes the original bug too then
I will provide a better version.
Best wishes
Mark
