Commitsa29bb6a14b...5c199d99f4narrowed down on addressing the escaping of hyphens in the dynamic creation of manuals whilst avoiding them in creating help texts. This lead to a sequence of slipping through hyphens adrressed by additional patches in aforementioned commit series. On the other hand, postprocessing dynamically man-generator created and statically provided manuals catches all hyphens in need of escaping. Changes: - revert the above commits whilst keeping man-generator streamlining and the detection of any '\' when generating help texts in order to avoid escapes to slip in - Dynamically escape hyphens in manaual pages using sed(1) in the respective Makefile targets - remove any manually added escaping on hyphens from any static manual sources or headers

.SH NOTES
|
|
This previous command syntax would perform two different operations:
|
|
.br
|
|
\fBlvconvert --thinpool\fP \fILV1\fP \fB--poolmetadata\fP \fILV2\fP
|
|
.br
|
|
If LV1 was not a thin pool, the command would convert LV1 to
|
|
a thin pool, optionally using a specified LV for metadata.
|
|
But, if LV1 was already a thin pool, the command would swap
|
|
the current metadata LV with LV2 (for repair purposes.)
|
|
|
|
In the same way, this previous command syntax would perform two different
|
|
operations:
|
|
.br
|
|
\fBlvconvert --cachepool\fP \fILV1\fP \fB--poolmetadata\fP \fILV2\fP
|
|
.br
|
|
If LV1 was not a cache pool, the command would convert LV1 to
|
|
a cache pool, optionally using a specified LV for metadata.
|
|
But, if LV1 was already a cache pool, the command would swap
|
|
the current metadata LV with LV2 (for repair purposes.)
