This commit only affects translation of RTLIL processes (for which

Due to the event-driven nature of Verilog, processes like

    reg x;

may never execute. This can be fixed in SystemVerilog code by using
`always_comb` instead of `always @*`, but in Verilog-2001 the options
are limited. This commit implements the following workaround:

Add newlines to help text for dfflegalize

I think these were probably missed by accident. Spotted because GCC
spits out lots of messages like this:

passes/techmap/dfflegalize.cc:114:7: warning: zero-length gnu_printf format string [-Wformat-zero-length]
  114 |   log("");
      |       ^~

(because we tell GCC that the first argument to log() looks like a
printf control string in log.h, and a zero length such string triggers
a warning).
