It seems to leave certain (inconsequential?) whitespace changes in place that
make it hard to compare a changeset in an automated way, e.g.:
-----
- local_parts = ${if
eq{$domain}{$primary_hostname}{+path_safe_localparts}{*}}
+ local_parts = ${if eq {$domain} {$primary_hostname}
{+path_safe_localparts} {*} }
-----
If it were just that I would suggest "diff -w" or one of the other
whitespace options, but I see from your next observation that that
would not be sufficient.

On another note, I’ve noted via the same parse that this in exim.conf:
-----
router_home_directory =
${extract{5}{::}{${lookup{${lookup{$domain_data}lsearch{/etc/userdomains}{$value}}}lsearch{/etc/passwd}{$value}}}}
-----
… gets parsed to this:
-------
router_home_directory = ${extract{5}{::}{${lookup
passwd{${lookup{$domain_data}lsearch{/etc/userdomains}{$value}}}{$value}}}}

^^ Note the conversion of the first “lookup” to a “lookup passwd”.
But, if I reflow the exim.conf a bit to:
-----
router_home_directory = ${extract \
{5} \
{::} \
{${lookup \
{${lookup \
{$domain_data} \
lsearch \
{/etc/userdomains} \
{$value} \
}} \
lsearch {/etc/passwd} \
{$value} \
} } \
}
-----
… then the conversion to “lookup passwd” doesn’t happen:
-----
router_home_directory = ${extract {5} {::} {${lookup {${lookup {$domain_data}
lsearch {/etc/userdomains} {$value} }} lsearch{/etc/passwd} {$value} } } }
-----
Is this an optimization of some kind in Exim, which the breaking up into
multiple lines is losing?
Thank you!
