+>>> less-than-ideal behaviour: links where the current language is unknown,
+>>> with `po_link_to = current`, always go to the master language,

+>>>> Thanks for taking care, thanks for these improvements!
+>>>>
+>>>> OTOH I consider any of these behaviours (either the brand new one
+>>>> = link to master language, or the alternative one = link to
+>>>> negotiated) as a regression. Any of these is contrary to what
+>>>> `po_link_to = current` is supposed to do according to the
+>>>> documentation.
+>>>>
+>>>> Let's be less technical, let me display my practical usecase
+>>>> (making this possible was one of the main reasons I initially
+>>>> implemented `po_link_to = current`).

+>>>> Summary: the current state of things is an annoying regression
+>>>> and it needs to be fixed.
+>>>>
+>>>> Context: I participate in building a Live system based on Debian
+>>>> Live; the project's multilingual website
+>>>> ([T(A)ILS](https://amnesia.boum.org/) is built using ikiwiki. A
+>>>> static / offline copy is shipped on ISO images; this is the way
+>>>> end-user documentation lands on the CDs. Note that no webserver
+>>>> runs on the Live system to serve this wiki, so `po_link_to =
+>>>> current` is compulsory. A user can choose her preferred language
+>>>> at boot time. Depending on her decision, The desktop shortcut
+>>>> that points to the embedded documentation (i.e. static wiki)
+>>>> links to a different entry point depending on the chosen
+>>>> language.
+>>>>
+>>>> The previous (documented) behaviour was deadly simple:  if I am
+>>>> presented a page in English (master language) it means it does
+>>>> not exist in my preferred language; the computer always displays
+>>>> me the best available version according to my needs. The new
+>>>> behaviour brings a troubling seemingly random factor into the
+>>>> user navigation experience and IMHO is a mess from a web
+>>>> ergonomics point of view (no content negotiation available,
+>>>> remember): I sometimes am shown an English page although it is
+>>>> fully translated in my language one click away, and on the
+>>>> contrary I sometimes I am shown the optimal page. This, is, well,
+>>>> interesting. This practically forces the non-English speaking
+>>>> website visitor to check the otherlanguages list on every single
+>>>> page to make sure *herself* there is nothing better available,
+>>>> and sometimes click on her preferred language link to get a page
+>>>> she actually can read.
+>>>>
+>>>> I unfortunately might not be able to dedicate the needed time to
+>>>> help fix this in a timely manner, so I don't want to urge anyone.
+>>>> Take care!  --[[intrigeri]]

+
+urlto() has a special-case for a zero-length first argument, but it
+produces a relative path even if the third argument is given and true.
+
+My `ready/urlto` branch simplifies this special case so it works. --[[smcv]]
