You know, looking at the output each time one runs update.php,

...category table already populated.
...have ar_parent_id field in archive table.
...have user_last_timestamp field in user_newtalk table.
...rev_parent_id column already populated.
protected_titles table has correct pt_title encoding.
Checking filearchive indices...
...have ss_active_users field in site_stats table.
...ss_active_users user count set...
...have rd_interwiki field in redirect table.
...transcache tc_time already converted.
Renaming eu_wiki_id -> eu_local_id... already done.
Altering all *_mime_minor fields to 100 bytes in size ... ok
Populating rev_len column
...doing rev_id from 943 to 1142

it is very hard to tell which lines

• changed nothing, vs.
• changed something

Apparently the last three lines above changed something. The rest changed nothing.

Even worse is if one is not a native English speaker, then reading
each line to figure out if it changed nothing vs. changed something is
even harder.

However don't get me wrong. I am not proposing translation work.
Instead I am just hoping that the lines that actually changed
something will stand out better, via indenting, prefixing, or
whatever.

E.g., /var/log/Xorg.0.log has:

Markers: (--) probed, (**) from config file, (==) default setting,

(++) from command line, (!!) notice, (II) informational,
(WW) warning, (EE) error, (NI) not implemented, (??) unknown.

So perhaps just have a * prefix pre-pended to lines that changed
something, with of course a note at top saying what the * means.
