+`notmuch-mua-prompt-for-sender' is over-engineered and often wrong.\r
+It attempts to detect when all identities have the same name and\r
+specialize the prompt to just the email address part, but this has\r
+several problems. First, it uses `mail-extract-address-components',\r
+which is meant for displaying email addresses, not general-purpose\r
+parsing, and hence performs many canonicalizations that can interfere\r
+with this use. For example, configuring notmuch-identities to\r
+("Austin <austin@example.com>"), will cause\r
+`notmuch-mua-prompt-for-sender' to lose the name part entirely and\r
+return " <austin@example.com>". Second, though less serious, the\r
+prompt specialization means the user can't enter a different name like\r
+they can if their identities have different names.\r
+\r
+This patch rewrites `notmuch-mua-prompt-for-sender' to simply prompt\r
+for a full identity, where the list of identities is derived from\r
+either notmuch-identities or the user's Notmuch configuration.\r
+\r
+The original code also did several strange things, like using `eval'\r
+and specifying that this function was interactive. As a side-effect,\r
+this patch fixes these problems. And it adds a docstring.\r
