/*
-** This module has a long and checkered history. First, it didn't burst
-** maildrops correctly because it considered two CTRL-A:s in a row to be
-** an inter-message delimiter. It really is four CTRL-A:s followed by a
-** newline. Unfortunately, MMDF will convert this delimiter *inside* a
-** message to a CTRL-B followed by three CTRL-A:s and a newline. This
-** caused the old version of m_getfld() to declare eom prematurely. The
-** fix was a lot slower than
+** This module has a long and checkered history.
**
-** c == '\001' && peekc (iob) == '\001'
+** [ Here had been some history of delimiter problems in MMDF maildrops ... ]
**
-** but it worked, and to increase generality, MBOX style maildrops could
-** be parsed as well. Unfortunately the speed issue finally caught up with
-** us since this routine is at the very heart of MH.
+** Unfortunately the speed issue finally caught up with us since this
+** routine is at the very heart of MH. To speed things up considerably, the
+** routine Eom() was made an auxilary function called by the macro eom().
+** Unless we are bursting a maildrop, the eom() macro returns FALSE saying
+** we aren't at the end of the message.

-** To speed things up considerably, the routine Eom() was made an auxilary
-** function called by the macro eom(). Unless we are bursting a maildrop,
-** the eom() macro returns FALSE saying we aren't at the end of the
-** message.
+** [ ... and here had been some more of it. ]
**
-** The next thing to do is to read the mts.conf file and initialize
-** delimiter[] and delimlen accordingly...
-**
-** After mhl was made a built-in in msh, m_getfld() worked just fine
-** (using m_unknown() at startup). Until one day: a message which was
-** the result of a bursting was shown. Then, since the burst boundaries
-** aren't CTRL-A:s, m_getfld() would blinding plunge on past the boundary.
-** Very sad. The solution: introduce m_eomsbr(). This hook gets called
-** after the end of each line (since testing for eom involves an fseek()).
-** This worked fine, until one day: a message with no body portion arrived.
-** Then the
-**
-** while (eom(c = getc(iob), iob))
-** continue;
-**
-** loop caused m_getfld() to return FMTERR. So, that logic was changed to
-** check for (*eom_action) and act accordingly.
-**
-** [ Note by meillo 2011-10:
-** as msh was removed from mmh, m_eomsbr() became irrelevant. ]
-**
-** This worked fine, until one day: someone didn't use four CTRL:A's as
-** their delimiters. So, the bullet got bit and we read mts.h and
-** continue to struggle on. It's not that bad though, since the only time
-** the code gets executed is when inc (or msh) calls it, and both of these
-** have already called mts_init().
