Update the IMAP server to reflect the flags for a single message before performing a "UID COPY".

Note
This does not sync the "deleted" flag state, because it is not desirable to propagate that flag into the copy.

◆ imap_fix_path()

char* imap_fix_path ( char  delim,
const char *  mailbox,

Fix up the imap path.

Parameters
delimDelimiter specified by the server, '\0' for C_ImapDelimChars
mailboxMailbox path
pathBuffer for the result
plenLength of buffer
Return values
ptrFixed-up path
Note
if delim is '\0', the first character in mailbox matching any of the characters in C_ImapDelimChars is used as a delimiter.

This is necessary because the rest of neomutt assumes a hierarchy delimiter of '/', which is not necessarily true in IMAP. Additionally, the filesystem converts multiple hierarchy delimiters into a single one, ie "///" is equal to "/". IMAP servers are not required to do this. Moreover, IMAP servers may dislike the path ending with the delimiter.
