- OpenFromFile opens non-blocking, fstat()s and accepts regular files
only. A directory made tellg() report a huge size and bad_alloc exit
the editor (reachable by Tab-completing a directory in the open
prompt); a FIFO blocked open() forever with SIGINT ignored; a device
node opened as an empty, file-backed buffer that saving then replaced
with a regular file. Files are read to EOF in chunks; a file too large
to load is reported, not fatal.
- Saving refuses to replace an existing non-regular file.
- Exceptions escaping a command handler are reported in the status line
and error log instead of propagating to main() and exiting, which lost
every unsaved buffer (unnamed buffers' journals are never recovered).
- Commands use non-throwing filesystem queries for existence checks,
the current directory and Tab completion (ENAMETOOLONG, EACCES or a
deleted working directory used to throw).
