He has a global +keybinding of "C-c s" for notmuch-search and this causes help in +tree-mode to hang. + +I have mostly diagnosed this: the problem comes that all the construct +help routines are inside a string-match/replace-match pair. Somewhere +in these routines the match-data is being stomped on (but I have to +admit I am not sure where). + +In any case putting the construct help routines inside a +save-match-data seems to fix it. + +This version is a bit ugly: I am not sure of the best way to deal with +the save-match-data macro. (I think it is best to have it round +everything that happens between finding the match and replacing the +match to avoid anything similar in future). + +This applies on top of the parent series. + +Any comments gratefully received! + +Best wishes + +Mark + +--- + emacs/notmuch-lib.el | 17 ++++++++++------- + 1 files changed, 10 insertions(+), 7 deletions(-) + +diff --git a/emacs/notmuch-lib.el b/emacs/notmuch-lib.el +index 7b8acb3..e98e073 100644 +--- a/emacs/notmuch-lib.el ++++ b/emacs/notmuch-lib.el +@@ -305,13 +305,16 @@ prefix argument.
