rmail-summary-by-regexp searches the headers of the messages in an
Rmail buffer and displays those that contain a header that matches the
user-provided regexp. However, in regard to the Subject: header, the
search is done against the "raw" header, not against the string after
encoded-words (=?...?= constructions) are processed. Given that in
all situations (other than when rmail-mime is in effect), Rmail shows
the decoded Subject: rather than the raw header, the search can easily
not find messages that the user expects to match. In extreme cases,
the user can copy the text of a message's Subject: header for use as
the argument to rmail-summary-by-regexp but no messages will be
reported in the RMAIL-summary buffer.
To demonstrate this, put one message in a mailbox file and replace its
Subject: line with:
Subject: =?UTF-8?Q?Re=3A_=5Bgit=2Dusers=5D_Re=3A_git_1=2E9=2E4=E2=80=8F_for_window_prompt_s?=
=?UTF-8?Q?h=2Eexe=3A_=2Fdev=2Fnull_No_such_file_or_dirctory?=
this decodes to:
Subject: Re: [git-users] Re: git 1.9.4 for window prompt sh.exe: /dev/null No such file or dirctory
Now execute:
C-M-s /dev/null RET
The user will expect to see the one message listed in the
RMAIL-summary buffer. But it will not be.
